Answer 2

To find the value of the expression -6 + 3x + 8 - 3.7x - 5 for the given values of x, we substitute each value into the expression and calculate the result.

Let's calculate for each value of x:

For x = -2: -6 + 3(-2) + 8 - 3.7(-2) - 5 = -6 - 6 + 8 + 7.4 - 5 = -12 + 8 + 7.4 - 5 = 3.4

For x = -8/1 (which is -8): -6 + 3(-8) + 8 - 3.7(-8) - 5 = -6 - 24 + 8 + 29.6 - 5 = -30 + 8 + 29.6 - 5 = 2.6

For x = -0.4: -6 + 3(-0.4) + 8 - 3.7(-0.4) - 5 = -6 - 1.2 + 8 + 1.48 - 5 = -7.2 + 8 + 1.48 - 5 = -2.72

Therefore, for x = -2, -8/1, and -0.4, the values of the expression are 3.4, 2.6, and -2.72, respectively.
